chetbox/ghoulio repository overview

⁠Ghoulio

A docker image to automate interaction with web pages. Uses Gecko-based SlimerJS⁠ under the hood.

⁠Usage

$ docker run chetbox/ghoulio URL CALLBACK_URL JAVASCRIPT

Opens URL and run JAVASCRIPT in the page. Makes a GET request to CALLBACK_URL with the result as the response query parameter.

JAVASCRIPT may make use of the following global functions:

• resolve(DATA) - Stop the process. JAVASCRIPT script should usually contain a call to close() to stop the process. Results in a callback with: {"success": true, data: DATA, url: URL}
• reject(ERROR_INFO) - Print out the error and stop the process. Results in a callback with: {"success" false, "error": ERROR_INFO, url: URL}
• callback(MESSAGE) - Fire a callback with: {"message": MESSAGE, url: URL}.

⁠Example

The following search for "boo" on Google and sends the results to RequestBin. You can see the results here⁠.

# Print Google search results
docker run chetbox/ghoulio https://www.google.com/search?q=boo http://requestb.in/wfyqwtwf "
resolve(Array.prototype.slice.call(document.querySelectorAll('h3.r'))
.map(function(a) {
 return a.textContent;
}));"

Any execution errors will cause the process to end. Use try ... catch to prevent this.
